.Nm
are as follows:
.Bl -tag -width blame
-.It Cm log [ Fl c Ar commit ] [ Ar repository-path ]
+.It Cm log [ Fl c Ar commit ] [ Fl r Ar repository-path ] [ path ]
Display history of a repository.
-If the
-.Ar repository path
-is omitted, assume the repository is located in the current working directory.
+If a
+.Ar path
+is specified, show only commits which modified this path.
.Pp
This command is also executed if no explicit command is specified.
.Pp
.Ar commit .
The expected argument is the name of a branch or a SHA1 hash which corresponds
to a commit object.
+.It Fl r Ar repository-path
+Use the repository at the specified path.
+If not specified, assume the repository is located at or above the current
+working directory.
.El
.It Cm diff [ Ar repository-path ] Ar object1 Ar object2
Display the differences between two objects in the repository.
